You must have not been cognitive during the time period.
We had our own dance crazes with Aunt Jackie/Go Stupid/Chicken Noodle Soup and of course Lite Feet. This was a good 2-3 years before Jerkin. In the getting lite era people used to wear skinny jeans, colorful clothes, and sneakers. The video below happened right outside my school and this was '07, and you already see the skinny jeans and in general more fitted jeans, purples, greens, browns, yellows, matching sneakers, etc.
The fashion was already trending to tighter clothes with the boot cut True Religion, Ed Hardy tees, B.B. Simons belts that dudes like Juelz, Jimmy, Max was wearing.
The alternative, creative hood kids that shop at department stores in SoHo and wore street brands was wearing tighter jeans. Ferg, Rocky, Teyana Taylor was on some different shyt and this is before they were famous.
